CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of priority of U.S. non-provisional application Ser. No. 16/566,247, filed 10 Sep. 2019, as a continuation thereof, and of U.S. provisional application No. 62/728,961, filed 10 Sep., 2018, the contents of which are herein incorporated by reference.

BACKGROUND OF THE INVENTION

The present invention relates to accessories for riding mowers and, more particularly, to a step and rail system for aiding physically challenged operators seating themselves on a riding mower.

Riding mowers, ride-on mowers, or tractor mowers are lawn mowers where the operator is seated. Typically, a mower stepping surface is provided for the would-be operator to step from the ground to the seat. People with certain physical disabilities or in a weakened state from age and/or illness, however, are sometimes not able to make it to the mower stepping surface and/or otherwise seat themselves on a riding mower, and thus, by definition, cannot operate it.

As can be seen, there is a need for a step and rail system to aid physically challenged individuals to seat themselves on a riding mower. The step and rail system embodied in the present invention provides a novel arrangement of steps and handrails that are mounted to the riding mower, aiding the operator to mount and dismount the seat of the riding mower. The novel arrangement includes two spaced apart horizontal rails running a substantial length of the riding mower, and wherein the horizontal rails provide a compound bend for widening immediately adjacent the seat relative to the mower stepping surface.

SUMMARY OF THE INVENTION

In one aspect of the present invention, a step and rail system for a riding mower includes the following: an intermediate step mounted to a front portion of the riding mower, the step disposed at a step elevation between an elevation of a support surface for the riding mower and an elevation of a mower stepping surface of the riding mower; two spaced apart rails extending from a rear portion of the riding mower to a front portion of the riding mower adjacent the intermediate step; and the two spaced apart rails are spaced apart a distance greater than a width of a centrally disposed seat of the riding mower.

In another aspect of the present invention, the step and rail system for a riding mower includes the following: a front mounting plate mounted to a front portion of the riding mower, wherein the intermediate step is attached to the mounting plate; a step plate attached to the front mounting plate; an intermediate step mounted to said step plate so that the intermediate step is disposed at a step elevation between an elevation of a support surface for the riding mower and an elevation of a mower stepping surface of the riding mower; two spaced apart rails extending from a rear portion of the riding mower to a front portion of the riding mower adjacent the intermediate step; the two spaced apart rails are spaced apart a distance greater than a width of a centrally disposed seat of the riding mower; a crossbar interconnecting the two spaced apart rails aft said seat; a left mounting plate and a right mounting plate attached to said rear portion so as to be rear attachment points for the two spaced apart rails, respectively; a mower stepping surface adjacent the front portion of the riding mower; and the two spaced apart rails are spaced further apart immediate adjacent said seat relative to adjacent said mower stepping surface.

These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

Broadly, an embodiment of the present invention provides a step and rail system adapted to frame a seat of a riding mower so that a physically challenged operator can assist themselves in mounting the seat. The step and rail system provides a horizontal support rail configuration of two spaced apart rails. The present invention includes a front mounting plate for an intermediate step and two rear mounting plates for supporting the two spaced apart rails as they extend from the rear of the riding mower to the front thereof. The horizontal support rail configuration may provide a compound bend fore the seat so that the horizontal support rail configuration is wider adjacent the seat as compared to the mower stepping surface. The narrower rail configuration immediately adjacent the stepping surface assists the physically challenged operator from the ground up to the mower stepping surface.

Referring to FIGS. 1 through 3, the present invention may include a step and rail system 10 for aiding physically challenged operators to sit on the seat of a riding mower. The step and rail system 10 may include a front mounting bracket 18, a step mounting bracket 20, and a step 22 for providing the step component, and a left rail 16, a right rail 14, a crossbar 12, and a right and left rear mounting bracket 24 and 26, respectively, for providing the rail component.

The front mounting bracket 18 operatively associates with a front portion of the riding mower 30 through conventional fasteners or the like. The front mounting bracket 18 provides a surface to attach the centrally-disposed step mounting bracket 20 and the front distal ends of the left and right rails 16 and 14 near the ends of the front mounting bracket. The front mounting bracket 18 may be an L-bracket or the like.

It should be understood by those skilled in the art that the use of directional terms such as horizontal, vertical, upper, lower, upward, downwardly, top, right, left and the like are used in relation to the illustrative embodiments as they are depicted in the figures, the upward direction (or upper) being toward the top of the corresponding figures, the downward (or lower) direction being toward the bottom of the corresponding figures, left and right correspond with the would-be operator sitting in the seat of the riding mower 30 shown in the corresponding figures, and horizontal is defined relative to the unshown supporting surface of the riding mower 30 in the corresponding figures.

The step brackets mounting bracket(s) 20 are attached to the front mounting bracket 18 and provide the support for the horizontal step 22. The step 22 may be positioned half the distance between the supporting surface/ground and the mower stepping surface 32 of the front of the riding mower 30, which is dimensioned for the non-physically challenged user of the riding mower 30 and the ground. The step 22 gives a person with limited range or in a weakened state the ability to overcome the height of the mower stepping surface 32 with an intermediate step 22.

The left and right rear mounting brackets 26 and 24 provide rear attachment points for the distal ends of the left and right rails 16 and 14, respectively. The rear mounting brackets 26 and 24 are attached with fasteners or other joining elements (such as welding) to existing holes in or to surfaces of the rear frame of the riding mower 30. The handrails have two, typically rounded, 90-degree transition bends 38 that allow the rails to attach to and interconnect the front mounting bracket 18 and the rear mounting brackets 26 and 24 to create a spaced-apart horizontal support rail configuration 100. The upper section of the left and right rails 16 and 14 may contain compound bends 28 that moves the rails away from the seat to allow more room for the operator. The space between the two horizontal support rail configuration 100 accommodates the seat of the riding mower 30, and thus aids the operator mounting said riding mower 30. A crossbar 12 may connect the two spaced-apart horizontal support rail configuration 100, adding lateral support by tying the rails together. The crossbar 12 is disposed rearward of the seat. The front mounting bracket 18 and step mounting brackets 20 may be cut from sufficiently durable material, such as aluminum, with the strength to resist repeated bending stress applied as a result of the use contemplated herein. The front mounting bracket 18 may attach to the front axle. The step 22 may be located between the front wheels but must be narrow enough to allow the front wheels to rotate 360 degrees as designed. The rear mounting brackets 24 and 26 may be made from material with the strength to resist repeated bending stress applied as a result of the use contemplated herein. The rear mounting brackets 24 and 26 may be attached by using existing holes in the mower frame. The handrail attachment points 18, 24, and 26 could be relocated and/or the step 22 can be relocated to accommodate specific user's disabilities and/or weaknesses.

The left and right rails 16 and 14 may be made from 1½-inch aluminum tubing and bent using a tubing bender. Once the distance between the front and rear mounting is determined the tubing may be bent to fit that measurement and welded to the mounting brackets 18, 24, and 26. All components may be TIG welded together. Aluminum may be used due to its strength to weight ratio. All elements are necessary as the parts are connected together to make one functional piece.

A method of using the present invention may include the following. The step and rail system 10 disclosed above may be provided. A would-be operator may grasp either the left and right rails 16 and 14, or both, to assist in stepping onto the step 22, which is approximately half the distance from the ground than the mower stepping surface 32, to step up to said stepping surface 32 so as to seat themselves on the seat, all while having the left and right rails 16 and 14 of the horizontal support rail configuration 100 in reach throughout the lowering and lifting process to and from said seat.

Additionally, the step and rail system 10 could be used to aid in accessing the seats of different types of equipment, for instance, tractors or other heavy-duty riding equipment.
